Hi Doug,

These are Siemens DICOMs and I really don't know what happened
to these T1 files, we just got them in this format. Only one out of 32
datasets went wrong, so I consider it as an incident. The workaround
with dcm2nii worked fine. Nevertheless, if you are interested I can
upload the dataset.

Is it a siemens dicom? If so, what happened to the ascii header? Did you

do something to the file? What are the contents of the image? Eg, a T1?

Hi,


I got an error during the first step in recon-all (Mac OS 10.6.8,

FreeSurfer v5.1.0). The  eror message in the log file is:


WARNING: file ...../MR.1.3.12.2.1107.5.2.18.41016.201008031106017688438785.dcm does not contain a Siemens ASCII header

has this file been anonymized?

ERROR: cannot unpack mosiacs without ASCII header.


This is strange because it is no mosaic file and all the files can be converted

without any problems with e.g., dcm2nii and viewed with OSIRIX.


Cheers,

Ed
